I have Moodle 1.9.3 site . I do create a "Question Bank" and I setup to have a quiz with "Essay" type from that "Question Bannk".
When I go to grade the quiz manually , I have to grade question by question (not student by student). My question is : "Can I change it to grade student by student ? And How ?"
Thank you for your concern !
In the quiz, go to Results -> Manual grading.
